In a large bowl, mix the raw shrimp, olive oil, Cajun seasoning, garlic powder, cayenne pepper, and a pinch of salt.
Toss until the shrimp are evenly coated with the spices.
Heat a cast iron skillet over medium-high heat. Add the seasoned shrimp and cook for 2-3 minutes on each side, until they turn pink. And set aside.
Meanwhile, warm the tortillas. Heat them in a skillet or grill for 30 seconds on each side, until they are warm and slightly charred. And set aside.
Now lay out the tortillas and spread a layer of thinly sliced cabbage, red onion, and chopped tomato on each one. Top with a few pieces of the cooked Cajun spiced shrimp.
Place slices of avocado, a sprinkle of chopped spinach, and a spoonful of taco sauce on top of the shrimp.
Garnish with fresh cilantro, squeeze lime juice over each taco, and serve immediately.
